Easy and Convenient Installation

Keep Your Home and Family Safe with In-Wall-Rated Speaker Wire

When you're running wire inside your walls, it's important that you use speaker cable that's approved for in-wall runs. This cable's CL2 certification means it passed safety tests administered by the Underwriters Laboratory (UL). The UL looks at heat generated from current flowing through wire, how quickly the cable will catch and spread fire when exposed to flame, and the wire's susceptibility to damage from external stresses. Also, be sure to check your local building and fire codes, and buy wire accordingly.

Gauge Selection

Different people will have their own opinions about what gauge is proper for what length. The quality of the equipment can also play a factor. The following is a general guide for picking gauges for certain lengths.

0 - 25ft: 18AWG

25 - 50ft: 16AWG

50 - 75ft: 14AWG

75 & up: 12AWG

Selecting the Correct Speaker Wire for the Application

Based on the following questions, use the table as reference to select the proper gauge size:

1. What is your speaker type (4&ohm;, 8&ohm; or 70-Volt)?

2. What is the acceptable power loss (11%, 21%, 37% or 50%)?

Move down the column to select the wire AWG size that meets your distance requirement in feet.

Note:

Attenuation = -10lg (Pout/Pin)

Attenuation 3dB is commensurate with a 50% power loss.

Example

The maximum distance for 12 AWG in a 4 Ohm speaker system with 11% or 0.5dB loss is 140ft.
